Hey guys. I'm finishing up a physics quiz and have come to one where the only notes I have for it are passed in on assignments. So help would be greatly appreciated.
The equation I think I should use is
Code:
A sled with a mass of 50kg is pushed on snow covered ground. The static co-efficient is 0.30, and the kinetic co-efficient is 0.10
i) Calculate the force needed to start the sled moving.
ii) Calculate the force needed to keep the sled moving at a constant speed.
iii) Once moving, calculate the force that must be applied to sled to cause it to accelerate to 3.0m/s.The equation I think I should use is
